Y This invention relates broadly to rolling mills, and more specificallyto an adjusting mechanism for the rolls of such mills.

The primary object of the invention is to provide, in association withthe roll-pressure adjusting' screws of a rolling mill, a mechanismwhereby eitherend ofthe top 'roll of the mill., may, independently ofthe other, be adjusted relative to the underlying roll for disposingsaid rolls in parallelism, and also whereby the opposite ends of the toproll may be simultaneously and unifoi'inlyadj usted to vary the width ofthe operating space between the rolls. i A further object is topiovide amechanism of the character mentioned which embodies means wherehyaccurate individual adjustment of the pressure .screws may be effectedwith promptness and'facility.

lilith these and other objectsl in view, th invention resides in thefeatures of construction, arrangement of parts and combinations ofelements which will hereinafterA be fully described, reference being hadherein to the accompanying drawings, in which n Figure 1 is alongitudinal section of a roll adjusting mechanism, or screw-down,embodying iny invention;

Figure 2 isan outer face view of the adjusting wheel and the partscarried thereby; and-d Figure 3 is an enlarged broken sectionillustrating a modification.

Referring to said drawings, designates the roll housings, and 21 and 22the roll adjusting pressure screws of `a rolling mill. Carried by saidscrews 21 and'22, respectively, are bevel gears 23 and 24C which have intheir upper faces centrally located seats upon which are receivedcircular flanges 26 and 27 formed upon head-pieces 28 and 29 andconfined in place by rings 30 bolted to the gears 23 and 24:. A

Each of llio head piecesk carries a swivel` like bearing 13 in which isournaled a lshaft 9. Mounted for independent rotation on said shaftadjacent to one 'end of the latter is a bevel pinion 3 which is disposedin operative relation to the adjacent bevel gear 23 and upon which isrigidly'niounted the hub por'- tion 31 of a disk or wheel 32 `adapted tobe rotated by hand in effecting roll adjustments, as will hereinafter beexplained. yAy second bevel pinion 10 operatively engaged with theROLL-ADJUSTING MECANISM.

2, or upon a bracket l carried by said bar, is

lever 5 which has pivoted Aupon the forward end thereof one end ofafpin`3.' Said pin is' movable through a guide-hole 34 provided thereforin said bar 2 and Vis adapted to be engaged with any one of numeroussmall holes or seats 35 providedvin a circular row in the wheel 32, saidrow being located inwardly with respect to and concentric' with the rim1 land said holes having an arrangement *in closely spaced relation, asshown in Fig. 2. A spring 12 carried by the bar 2 underlies the oppositeend of the lever 5 for normally maintaining the latter in a positionwherein the thereby s carried pin` 3 is projected through a registeringhole 35 of the wheel 32, thus to render the shaft 9 rotatable with saidwheel. Pivotally mounted in an appropriate position on the bracket 7carried by the bar 2 is a cam 36 having its face disposed in engagementwith said lever `5.y Said cam has associa-ted therewithy a hand lever 6whereby -rotary movement may be imparted thereto for thrusting inwardthe rear end of the lever 5 against the tension of the spring 12 foreffecting withdrawal of the pin 3 from the engaged hole 35 of the wheel32V to release the latter.

As is made manifest by the foregoing desoription, the end of the rolladjacent to the screw operators end of the mill may be in-v dependentlyadjusted by rotation of the hand wheel 32 following disengagement of thelatter from the shaft 9, effected by rot-ation of the cam 36 to theposition in which the levercarried pin 3 is disengaged fromsaid wheel.v

Also, the opposite end of said roll may be independently adjusted byrotation of the bar 2 following disengagement of the wheel from theshaft, effected lin the manner just described. Or, the two ends oftherollmay b@ unifornrly adjusted by rotation of the Wheel when the latterle inteengaged with the el'ml' 9 through die intermediacy of the pin 8,bar 2 and hub.

A' eount-erweight 17 is preferably Carried by the bor 2 at die endopposite that on Wliieli rlie lever 5 is mounted, said ooun'terweiglitbeing employed lo balance the Weight of die two ends.

The alternate structure disclosed in Fig. 3 is designed `for use ineases Where it is clesiroole or necessary to locale the pinion 8 at theSide of lie bevel gear 23 opporsi ,e lire hund Wlieel. ln Juhiefir-rangement Jelle pinion is fixed upon the inner end of :i sleeve lewhich einbraoee the sluit 9 and which iS rotatable in rho bearing 3.Fixed upon lie outer end of said sl eve is o oollzu. l5 upon which ismounted the hub portion 3l of the Wlieel Qbviouely, ille operai-ions toeffect the dineront adjmsl'n'ienlri are precisely elle saine es in theeuse of eniiiloynieut of elle conetruoion shown in Figs, l a` io 2.
